"a white person's viewpoint of education."
A) This is a little racist :)
B) "Education = Daycare" is easily proven, right from the article -> Finnish kids don't start school until they are 7 years old (!) and they are #1 in the world for 'outcomes'!
So it would seem that 'doing nothing put let kids play, in a semi-structured way' is equivalent to sending them to school.
Ergo, one could argue that 90% of 'early childhood education' is, in fact 'daycare'.
That your friend 'runs here kids like soldiers' - simply means she has a lot of control - it does not mean they are necessarily learning. Possibly they are learning more self-discipline? And other behaviours, but I wouldn't take that it means more 'learning'.
As long as they are socializing, maybe learning some words, some basic reading - the rest is playtime.
As for your 'racist' (I mean, it's kind of racist, certainly near 'dog whistle territory') comment - this is the reason people voted for Trump - when someone makes a comment somewhere about something innocuous - and then someone says 'racist'. It would be funny if it weren't true. Look where we are now.
